From: Matt Flax flatmax@flatmax.org
The cs4265 driver declares the "MMTLR Data Switch" register setting with a 0 register value rather then the 0x12 register (CS4265_SPDIF_CTL2). This incorrect value causes alsamixer to fault with the output : cannot load mixer controls: Input/output error
This patch corrects the register value. alsamixer now runs.
